Abstract

Purpose of the study: The importance of physical fitness in volleyball and its application in physical education which has not been maximized has encouraged research on the analysis of the impact of physical fitness on volleyball learning in relation to a longitudinal review of the aspects of speed, strength, and flexibility from the perspective of a sports pedagogy approach. Methodology: This study uses a longitudinal approach to analyze changes in aspects of learning evaluation and physical fitness of students over a period of 24 weeks involving three main parameters, namely: strength, speed, and flexibility through test instruments, to then be analyzed using repeated measurements of one factor (ANOVA) and measuring effect size with Hedges' g. Main Findings: The results of the study revealed that volleyball learning has a positive impact on students' learning achievement patterns and physical fitness in terms of speed, strength, and flexibility viewed from sports pedagogy. The implications of these findings are relevant to the development of physical education curricula and sports training programs along with their assessments that provide a scientific basis for planning sustainable training programs. Novelty/Originality of this study: The analysis of volleyball learning and its impact in the field of physical education evaluation in this study focuses on analyzing the sports pedagogy approach so that it not only analyzes the impact of learning but also develops an analysis related to aspects of physical fitness and learning as a whole using a longitudinal review from a sports pedagogy perspective.

Abstract

Indonesia's National Selection for State University Admission (SNMPTN) for Sports Science programs has shifted from practical motor skill tests to portfolio-based assessment, raising concerns about validity and reliability in measuring motor competence. This study examined the validity and reliability of portfolio assessment by comparing it with direct motor skill tests as the criterion measure. A quantitative descriptive-verificative design involved 50 Physical Education students at Jenderal Soedirman University with complete portfolio and practical test data. Four motor skill domains were assessed: hand-eye coordination, agility, lower-limb muscle power, and endurance. Statistical analyses included Wilcoxon test, Spearman's correlation, Intraclass Correlation Coefficient (ICC), Bland-Altman analysis, and error measurements. Results showed portfolio scores consistently overestimated performance with significant differences in three domains (p ≤ 0.001). Spearman's correlations ranged from moderate to strong (ρ = 0.432–0.814), yet ICC values indicated low-to-moderate absolute agreement except for lower-limb muscle power (ICC = 0.800). Bland-Altman analysis revealed systematic positive bias with wide limits of agreement. These findings suggest portfolio assessment is inadequate as a standalone instrument for selecting candidates based on motor skills and should serve as a complementary tool to standardize direct practical tests in Sports Science admissions.
